When adding simple text, and editing it, the font size is also changed in the text editor.
The problem is, if you're adding some small text, like font size 4 or less, it's almost impossible to read while editing it. It's not too small in the video, just in the text editor.
I would like to suggest always keeping the text the same size in the text editor, so you can read what you're writing/editing. The size in the text editor doesn't relate to the size in the video anyway, so there isn't really any point in it changing size there.
